Title: Improvements in or relating to fluid pressure control mechanism for variable speed gearing
IPC: F16H61/02
Filed: 1930-01-27
Abstract: 351,505. Controlling variable-speed gearing. SALERNI, P. M., 23, Carlton House Terrace, London. Jan. 27, 1930, Nos. 2811 and 31595. [Class 80 (ii).] Fluid-pressure control mechanism for variablespeed gearing comprises a single cylinder 5, Fig. 1, or piston 6 moved by fluid pressure and connected to so as to operate gear control members performing different functions, such as 2, 3, 4. Members 2, 3, 4 may be the locking-pawl and clutch operating parts for epicyclic gearing in casing 1 constructed as described in Specifications 347,092 and 347,165. Piston 6, Figs. 1 and 3, is fast on a fixed hollow rod 7 and cylinder 5 moved relatively thereto carries cam bowls 21, 22 for operating lever members 2, 3, and carries a link 23 for operating a lever 24 engaging clutch control member 4. Springs 23a are for synchronizing the.clutches. Inside rod 7 is a barrel valve 8 with ports 9 fed from an inner fixed tube 12 carrying pressure oil. When valve 8 moves to the left, ports 9 uncover fixed ports 11 to the left of piston 6, so that cylinder 5 moves also to the left. Through lever 19, valve 8 is returned to the right to close port 11. Similarly when valve 8 moves to the right, a port 10 is opened and afterwards closed by the following displacement of cylinder 5. The valve 8 is controlled through a sleeve 13 upon which lever 19 is pivoted and which has a definite position for each speed configuration of the variable gearing. The sleeve 13 is moved by a lever 14, which, as shown in Fig. 1, may be operated from a handlever 18 on the steering column 17 of a vehicle. The lever 14 may alternatively be operated by an automatic control shown in Fig. 2. A pump 29 driven proportionally to the vehicle speed forces oil into a fixed dynamostat cylinder 25 containing a piston 26 connected'to the same lever 14. This oil escapes through a valve 32 set to produce a definite range of speeds of the vehicle. Oil pressure on piston 26 acting against spring 26a varies with the vehicle speed and produces stepped displacements of lever 14 locked by a ball 33, such displacements effecting definite speed changes in the gear-box. The oil pressure in the dynamostat cylinder 25 and hence the speed ratio of the gearing may be influenced by a pendulum or gravity mass 34 in response to acceleration of the vehicle or to road gradient. Lateral displacement of the pendulum opens to exhaust 38 a port 37 leading from the cylinder 25. Specifications 346,846 and 347,093 are also referred to.

Title: Improvements in colour photography
IPC: G03C7/04
Filed: 1931-01-28
Abstract: 371,477. Colour photography. CHAPMAN, W., 71, Grovelands Road, Palmers Green, London. Jan. 28, 1931, Nos.2815, 2816, and 5002. [Class 98 (ii).] In the production of multi-colour screen positives or copies from multi-colour screen negatives or originals, a doubled image of the negative is projected on to the positive by means of a plate or prism of iceland spar or quartz or other image doubling device to obviate the necessity for registration. As applied to twocolour, ruled screens, the prism &c. is arranged between the projection lens and the positive and is adjustable both angularly and axially so as to form two images of equal intensity overlapping by the pitch of the negative screen rulings. The positive screen may be any suitable two-colour screen adapted to analyse the light from the negative ; with a ruled positive screen the rulings are so located in relation to those of the negative as to avoid moire effects. For three-colour work, the screen pattern is of known type comprising a regular succession of monochromatic lines of one colour between which are lines composed of alternating equal rectangles or squares of the other two colours ; the image-doubling device is so oriented that the image displacement is equal to the length of one of the twocolour elements in the direction of the monochromatic line and varies from the width of a monochromatic line to that of a two-colour line in a direction at right angles. The reproduction may be of enlarged or reduced size.

Title: Method and device for forming reinforced foundation piles with an enlarged base
Inventor: PICKMAN EDWARD
IPC: E02D5/44
Filed: 1952-02-04
Abstract: 713,362. Piles. COMPAGNIE INTERNATIONALE DES PIEUX ARMES FRANKIGNOUL. Feb. 4, 1952, No. 2945/52. Class 68(2) A pile is formed by driving a tube 1 into the ground by striking on an adherent plug 2 of concrete or the like, Fig. 1, holding the tube stationary when the required depth has been reached, ramming the concrete plug out of the tube thereby forming and filling a cavity beneath the tube, positioning a rigid body 3, preferably of concrete, on top of the rammed concrete, placing more concrete on top of the body 3, resuming the ramming until, as shown in Fig. 2, the body 3 reaches the required depth below the tube as indicated by the hooked ends 7 of the attached reinforcements 5 resting upon the top of the tube and until sufficient concrete has been laterally displaced to form a bulbous foot of the required depth and volume, and, finally, finishing the pile in any desired manner, the tube 1 being either withdrawn or left in the ground. Alternatively, the required distance between the body 3 and the foot of the tube may be obtained wholly or partly by raising the tube relatively to the body. If the tube 1 is finally to be removed. the hook ends 7 are sheared off. The upper ends of the reinforcements may be secured to and located by a stiffening ring which rests upon the tube when the body 3 is to be held stationary during the formation of the bulbous foot. The upper face of the body 3 is preferably formed to deflect the concrete laterally. The tube , may be driven by blows on a mandrel resting both on the upper edge of the tube and on the concrete plug. Alternatively, the tube is provided with a loose driving-point and is driven by blows on its top. A quantity of concrete is placed over the driving- point and is expelled, with the point 1 from the tube when the latter has reached the required depth. The,reinforcement assembly is then lowered into the tube and further concrete additions and ramming builds up the bulbous foot as before The body 3 may rest directly on the driving-point or, as in Fig. 6, may be integral with the driving- point 13. The lateral displacement of the concrete is impeded by the reinforcement wires so that the bulbous foot comprises a number of lobes. To reduce this number, a few thick rods 14 may be embedded in the body 13, Fig. 6, and, at a level above the foot, are welded to a reinforcement cage 12 of more numerous thinner rods. The thick rods may extend with the thin rods to the top of the tube.

[Also in Divisions F1 and F4] An electric furnace 1 delivers successive doses of molten metal 2 through an outlet pipe 3. Compressed gas enters when a valve 4 is opened so that the metal 2 rises up the pipe 3 until it actuates a detector 7. This causes a chamber 5 to discharge a predetermined weight of compressed gas into the furnace 1, through refractory therein, so that the required metal dose is discharged as determined by a timer 8 and the gas pressure in the furnace 1 is maintained. The timer 8 eventually causes the valve 4 to discharge gas to air so that the gas pressure drops to atmospheric. Reference has been directed by the Comptroller to Specifications 990,850 and 803,343.
